我遵循了这里找到的说明，并试图修复我的旧Eclipse + SDK + ADT，但没有运气。基本问题是一样的;我仍然得到错误消息:

此Android SDK要求Android Developer Toolkit版本23.0.0或以上。当前版本为22.6.3.v201404151837-1123206。请更新ADT到最新版本

但是我的eclipse找不到更新，也不能将ADT 23作为新软件安装。所以我不能在我的工作区编译我的旧项目。

I tested a fresh eclipode bundle for Windows 8, followed instructions found from Android's developers page, step by step, and it worked fine. So it seems that the Windows Eclipse build is not broken. But I wan't use my Linux installation, my old Ubuntu 10. It seems obvious, that to getting the Linux Eclipse environment working again, I must install a new Eclipse bundle, my old Eclipse won't ever see updates for ADT 23 to get things working. Again, these intructions are for Linux developers that wan't to get their old workspace projects working again without changes in the developing environment, except you must install a new Eclipse bundle, but after that your projects will work as well as before the version 23 SDK/ADT-mess.

If you are an Android developer you want to be sure, that you developing environment won't be messed up. Backup: ~./android (Here are your developer keys) Your old SDK dirrectory Your workspace Download the Eclipse bundle, Get the Android SDK. Follow instructions, create directory ~/Development and unzip bundle there. You get Eclipse and SDK directories. Start Eclipse from that directory Eclipse asks for a workspace. You can give it the old one. In Eclipse settings set SDK as downloaded SDK. Start Android SDK manager and download tools, Android versions you use and extras said in the Android developer tool page instructions You should now be ready to compile your old projects again, but for me it was not that simple. My old projects had errors. So open problems windows and you get to know that annotation.jar is missing. So you must copy annotations.jar from your old SDK, from, the backup you made, or from the older sdk.zip explained in this thread to <new SDK>/tools/support/annotations.jar

在那之后，我可以使用我在Ubuntu中的旧工作区，并在Android设备上编译和启动应用程序。就是这么简单。谢谢谷歌;-(

使用developer.android.com上发布的ADT包，其他答案对我来说都不起作用。

我最终下载了最新版本的Eclipse(不是ADT包)，然后通过菜单帮助→安装新软件→进入https://dl-ssl.google.com/android/eclipse (@RED_提到过)安装ADT插件。

我还必须更新我的工作空间以指向我以前的工作空间，而且大多数东西似乎都恢复了。

顺便说一句:这似乎是迁移到Android Studio的好时机……

完美的答案是。输入下面的路径，复制它们 Macintosh HD应用程序adt-bundle-mac sdk platform-tools 然后解析回到Macintosh HD应用程序adt-bundle-mac sdk tools， 最后，编辑文件Macintosh HD adt-bundle-mac sdk tools plugin。道具，例如plugin.version=21.0.0。 重新启动eclipse。一切都很好。

我也遇到了同样的问题，并且解决了它。你需要完全从Eclipse中卸载Android插件(从“about”部分..)，包括跟踪视图..

然后再次添加ADT插件(https://dl-ssl.google.com/android/eclipse/)并安装它。

问题解决了!

我猜这是SDK管理器或ADT插件更新机制的bug…

这对我很有用:)

如果由于某种原因，你安装了ADT预览版，需要恢复到当前稳定版，你不能使用对话框来安装“新”软件，因为你想要的实际上是一个旧的软件。而是这样做:

打开帮助>关于Eclipse…在Windows或Linux上。在Mac上，使用应用程序的菜单>关于… 点击“安装详情”按钮。 选择“安装历史记录”页签。 选择前面的配置之一。 点击底部的“恢复”按钮。
